So, any property that's available in those tags can be overridden on a per-plastic basis. Same with any top-level XML tag. This includes skirt behavior, infill behavior, top & bottom layers, etc. You can also nest top & bottom layers, support behavior, infills, etc. inside of the quality elements, like I do here:

To get this XML, export your settings as an FFF. Merge your tuned settings into my base-line profiles, consolidate them, and re-merge them back together. Any questions about specifics, please feel free to ask. Enjoy!

thanks Insta,
is it possible to modify your FFF files in S3D and save rather than in XTML?
I am lost when it comes to looking at lines of code and I don't want to make mistakes.
I am getting better with the settings in S3D and wouldn't mind just tweeking the FFF files when needed.

I am using your FFF profiles and liking them. The only problem is the ending script is raising the Z axis after printing so it is knocking over my prints and breaking them.
Did I do something wrong with the scripts?
